Scientists combine graphene foam, epoxy into tough, conductive composite but as light as pure epoxy. Rice University scientists have built a better epoxy for electronic applications. Epoxy combined with “ultrastiff” graphene foam invented in the Rice lab of chemist James Tour is substantially tougher than pure epoxy and far more conductive than other epoxy composites while retaining the material’s low density...

The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. Data from a worldwide array of telescopes, including ESO’s planet-hunting HARPS instrument, have revealed this frozen, dimly lit world. The newly discovered planet is the second-closest known exoplanet to the Earth and orbits the fastest moving star in the night sky. This image shows an artist’s impression of the planet’s surface.

A planet has been detected orbiting Barnard’s Star , a mere 6 light-years away. This breakthrough is a result of the Red Dots and CARMENES projects, whose search for local rocky planets has already uncovered a new world orbiting our nearest neighbour, Proxima Centauri.

The planet, designated Barnard’s Star b, now steps i...

Use of organophosphates has lessened, but risks to early brain development still too high. Public health experts have found there is sufficient evidence that prenatal exposure to widely used insecticides known as organophosphates puts children at risk for neurodevelopmental disorders.

In a scientific review and call to action published in PLOS Medicine, the researchers call for immediate government intervention to phase out all organophosphates...

A new approach to controlling magnetism in a microchip could open the doors to memory, computing, and sensing devices that consume drastically less power than existing versions. The approach could also overcome some of the inherent physical limitations that have been slowing progress in this area until now.

Researchers at MIT and at Brookhaven National Laboratory have demonstrated that they can control the magnetic properties of a thin-film material simply by applying a small voltage...
